• Visual C# Typed Dataset - No generated code?

  I'm using the designer(s) to create a typed dataset in Studio 2005. I get an XSD and an XSS file but get no 'cs' file or 'designer.cs' file. The 'Show All Files' option in the solution explorer is dimmed but seems to be 'turned on' because I can exclude a file and still see it in the list. There are no complaints from the wizard. I searched the C: drive thinking maybe the generated code got placed somewhere else by mistake. Nothing. I've tried this a couple of different ways including using a fresh project. I am pretty sure that this was working just fine at one point in time. The only thing I've done to the environment since then had to do with the ASP.NET AJAX Beta and the CTP for the same. Any ideas ...Show All

• Visual Studio 2008 (Pre-release) accessing image pixels for images from siteoforigin

  creating a BitmapSource from a siteoforigin pack uri (pack://siteoforigin:,,,/asdf.jpg) in an XBAP app. my assumption was that i could access the pixels (CopyPixels) of the image since it was served from siteoforigin ... but i'm getting a SecurityException should this be working as a workaround, i saw another post that ended up using System.Drawing.Bitmap. Thanks, casey ok, ends up that CopyPixels works fine on the initial URI load, but PixelFormat.BitsPerLength was throwing the SecurityException ... so now i'm just hardcoding that value. but now the problem i'm getting is after doing some pixel manipulation, i put it back into a BitmapSource, and perform a ScaleTransform to end up with a Tran ...Show All

• Visual Basic ComClass and backward compatibility

  Can anybody tell me the recommended way to expose VB.NET classes to COM if we expect the interfaces to change The Microsoft documentation recommends using the ComClass attribute (or template) for classes that need to be exposed to COM, but ComClass doesn't seem to have any provision for backward compatibility when I later add properties or methods to the class. If I just add public members to the VB.NET class, I get a COM interface with the same IID but with additional members. This violates the COM rule which states that COM interfaces must be immutable. Clearly I need to assign a new InterfaceID to the VB.NET class, while still implementing the old interface, and I am struggling to find any documentation on how to do this in a VB.N ...Show All

• Visual Studio 2008 (Pre-release) Select Shape element by clicking inside

  I have added few shape elements to the Canvas. In MouseDown function, i can select the element using InputHitTest Method. c# code for rectangle: ell = new Ellipse(); ell.Width = 100; ell.Height = 100; ell.Stroke = Brushes.Blue; ell.StrokeThickness = 2.0; Canvas.SetTop(ell, 25); Canvas.SetLeft(ell, 25); eCanvas.Children.Add(ell); InputHitTest returns the Ellipse element by clicking only on edges, but not when user clicks inside the ellipse. I notice that by filling the element it is possible to select the ellipse, but would like to do without filling it. Is it possible to select/highlight the ellipse element, if user clicks inside the rectangle box If you set Fill="Transparent" (or, from code, el ...Show All

• SQL Server HELP!! SQL Server Express 2005 engine connection to my DB

  Preface, I am just starting to learn about database and web development. I installed VS.net 2005 which updated my web site project file and automatically attached it to a database. It connected to ".\app_data\aspnetdb.mdf". However it messed something up and the connection didn't work. If I create a project from scratch, it connects to its DB just fine, but not my upgraded project. However, when I publish my web site, I need to use ODBC. So, my thought was to simply set up the system locally in a way that will make it easy to connect on the web site. I was told to add a system DSN to the "Microsoft ODBC Administrator". I tried to add a "SQL Server" and give it the database name but it failed to connect. ...Show All

• Visual Studio Express Editions Answer VB 2005 - Compositing Operations (C.O.)

  Hello Community! I'm quite new in VB (just since November06 ) and I'm looking for a fast way to overlap greyscale bitmaps in VB2005 (i.e. for every pixel R=G=B). I tryed to use the alpha-blending tchnique but it doesn't fit my porpouses (after I perform the C. O. the overlapping region is darkned). I would like the overlapping process to be a lightening process (the resultant color is always at least as light as either of the two costituent colors). In particular overlapping any color with white should produce white. Overlapping any color with black should leave the original color unchanged. I found an interesting program in VB6 that seems to to that http://www.vbaccelerator.com/home/VB/Code/vbMedia/Image_Processing/Compositing/arti ...Show All

• Visual Studio Team System SP1 - source control explorer tree view

  Will SP1 fix the issue that many operations cause the tree to refresh and lose your current location in the source tree That one is pretty annoying when trying to do multiple operations at a particular point in the hierarchy. Thanks for the update. Too bad this couldn't make it into the SP, but glad it will be fixed in the next release. As we are going through this with many of our users, I listen to some of the comments made when they see things like this and they do contribute to the overall feel of stability (or lack there of ) in the product. These things give it the sort of 1.0 feel, that you don't see in the latest VSS 2005 for example. We're trying to run larger evaluation groups to see how a ...Show All

• Visual C++ "Layered" precompiled headers

  Hi, I'm reading the book "C++ templates, the complete guide", and in section 6.5 the writers suggest to use layered precompiled headers. With that they mean to have multiple precompiled headers, but also to have a precompiled header to use another precompiled header, as if it inherits the other precompiled header. For instance, have one header containing all std includes like vector, list, string etc. This is a header that is unlikely to change a lot. You will create the first precompiled header from it. Let's say we put it in std.h. The second precompiled header need all stl headers and some of our own, which are likely to change every now and then. We want to avoid recompiling the stl headers when a change is made in t ...Show All
